Back from hols to find that the closed mind of JP is back in circulation!
THE CREW WERE NOT WHERE THEY THOUGHT THEY WERE, ie they thought they were faced with a hill about 300 or so feet high. as they pressed on in IMC.
You can repeat this as often as you like, but it will still be your theory and not fact.
Miss-plotting the light house is irrelevant. In VFR flight, the TANS is a tool to help you find the waypoint, which you will then see. Any suggestion that the crew intended to use TANS to fly in IMC within 500ft and 500 metres of cumulo-granite is frankly absurd.
It is a possible explanation, however, and must be weighed as evidence. Unfortunately for your theory, in order to find the pilots guilty of Gross Negligence, that evidence must prove BEYOND ANY DOUBT WHATSOEVER that that is what happened.
There is not, nor ever will be, such evidence. Therefore the crew MUST be given the benefit of considerable doubt.
Remember that the rules of evidence were expressly in place to protect dead men from kangaroo courts.
Banggaero's post of 2/6 1607 says it all.
